In biochemistry and pharmacology , the Hill equation refers to two closely related equations that reflect the binding of ligands to macromolecules, as a function of the ligand concentration. A ligand is "a substance that forms a complex with a biomolecule to serve a biological purpose" ligand definition , and a macromolecule is a very large molecule, such as a protein, with a complex structure of components macromolecule definition. Protein-ligand binding is an example of this kind of binding, which typically changes the structure of the target protein, thereby changing its function in a cell. The distinction between the two Hill equations is whether they measure occupancy or response.

Chemometrics is the science of extracting information from chemical systems by data-driven means. Chemometrics is inherently interdisciplinary, using methods frequently employed in core data-analytic disciplines such as multivariate statistics , applied mathematics , and computer science , in order to address problems in chemistry , biochemistry , medicine , biology and chemical engineering. In this way, it mirrors other interdisciplinary fields, such as psychometrics and econometrics. Chemometrics is applied to solve both descriptive and predictive problems in experimental natural sciences, especially in chemistry. In descriptive applications, properties of chemical systems are modeled with the intent of learning the underlying relationships and structure of the system i.
